Here are some runnable examples to help you get started with common use cases.

​
Express API Server

This example shows how to create a simple Express.js API endpoint that uses the SecureLend SDK to fetch loan offers. 
import express from 'express';
import { SecureLend } from '@securelend/sdk';

const app = express();
const port = 3000;

const client = new SecureLend({
  apiKey: process.env.SECURELEND_API_KEY,
});

app.use(express.json());

app.post('/get-offers', async (req, res) => {
  try {
    const { amount, term, businessType } = req.body;
    if (!amount || !term || !businessType) {
      return res.status(400).json({ error: 'Missing required parameters.' });
    }

    const offers = await client.getLoanOffers({ amount, term, businessType });
    res.json(offers);
  } catch (error) {
    console.error('API Error:', error);
    res.status(500).json({ error: 'Failed to fetch loan offers.' });
  }
});

app.listen(port, () => {
  console.log(`Server running at http://localhost:${port}`);
});
To run this example:
  1. Save the code as server.js.
  2. Run npm install express @securelend/sdk.
  3. Set your API key: export SECURELEND_API_KEY='your_key_here'.
  4. Start the server: node server.js.
  5. Send a POST request to http://localhost:3000/get-offers with a JSON body.
